Today we celebrate a new period in Japanese history, the Reiwa period. This ends the Heisei era, which began back in January 8th 1989, and although the change is not likely to be noticed in the west it is a major event in Japan.
We thought, with the end of the era, it was worth looking at the 10 most influential fighters of the Heisei era.
Just a caveat, before we begin, by influential we're not looking at the fighters who were the most successful during the era, but those who had a long last effect on the sport, specifically in Japan. Those who forced changes, influenced fighters or inspired fighters who followed them. To be considered they had to have fought between January 8th 1989 and April 30th 2019.
10-Takashi Uchiyama (24-2-1, 20) - The Watanabe Wonder
Several fighters on this list have gotten here due to their influence with fighters who have followed in their footsteps, or fighters who have turned their hand to promoting. Takashi Uchiyama on the other hand helped put the gym he was fighting for on the map. The Watanabe Gym had been opened for a few years but didn't really have a star to focus on, they lacked a fighter who could help attract top prospects and a man who carry the gym. In Uchiyama they had that star. Uchiyama's long reign as the WBA Super Featherweight champion, from 2010 to 2016, made his one of the major faces of Japanese boxing and he would inspire the Watanabe Gym, which is now regarded as one of the best in Japan. His effect on the Watanabe gym today has lead to fighters like Hiroto Kyoguchi and Ryoichi Taguchi becoming major forces. He's now running a gym of his own, and it's clear that Uchiyama's influence is going to continue well into the future.
9-Katsuya Onizuka (24-1, 17) - Superstar Spanky K
Popular fighters are influential due to their ability to draw a crown, get people talking and get eye balls on the sport. That was certainly the case with Katsuya Onizuka, who's popularity was huge in the 1990's. He turned professional in 1988 and would fight through to 1994, running up 5 defenses of the WBA Super Flyweight title, and even having a video game released with his likeness in Japan. Onizuka was certainly controversial, with numerous suspect wins, but his popularity kept people interested and kept watching. Following his retirement he would train fighters in Fukuoka, work for TBS in a commentary position and continue to have a pretty notable impact in the sport, much more so than fans in the West would realise.
8-Kazuto Ioka (23-2, 13) - Bar setting prodigy
The Osakan boxing scene is the second biggest in Japan, behind that in Tokyo, and for the better part of a decade the face of Osakan boxing was Kazuto Ioka. He drew huge TV rating, he was crowned as super prospect from his debut and he would, famously, win the WBC Minimumweight title in just his 7th bout. His career has been remarkable, winning world titles in 3 divisions, and chasing a 4th divisional world title. He's notable won an all-Japanese unification bout, a real rarity, challenged for a 4th divisional world title and set the mark for fewest fights to a world title, a mark that has since been beaten by Naoya Inoue and Kosei Tanaka. Ioka put a marker down for the newest wave of Japanese fighters, and really helped kick start the era of the Japanese super prospect.
7-Hozumi Hasegawa (36-5, 16) - Hyogo Hero
We're going to mention a man who inspired a generation of fighters a little bit further down this list, but Hozumi Hasegawa also fills that role excellently. In fact Hasegawa ois the man many current fighters cite as an inspiration, especially those in the Hyogo region. He was, for a long time, the one fighter from Hyogo who kept the region on the map, he was "The Ace" of Japan for years, a multi-time JBC MVP, a 3 weight world champion, a sensational fighter in the ring and someone who's appeal did actually cross over from Japan to the West. Hasegawa began his career in 1999 and despite some early defeats he would go on to win world titles at Bantamweight, Featherweight and Super Bantamweight, he was a TV star in the ring, with a great style to watch and with a list of notable names on his record. He wasn't the megastar that some had anticipated, but he was a big name, and the face of Japanese boxing during a little bit of a transition period in the 00's
6-Sugar Miyuki (11-1, 4) - Female punching pioneer
Women's boxing today is thriving in Japan, and Kasumi Saeki recently showed how good the top youngsters are. We've recent world champions like Naoko Fujioka, Ayaka Miyao, Etsuko Tada and Shindo Go all make their mark but the real OG is Sugar Miyoshi. A fighter you won't easily find on boxrec, where she's listed under her birth name of Nojima Miyuki and has an offiial record of 1-1. Miyuki was oriinally a Shoot Boxing fighter, a style more similar to kick boxing than regular boxing, but would turn to boxing in 1995, years before the JBC would recognise female boxing. In 1997 she would go on to win the IWBF Minimumweight title, becoming Japan's first female world champion. Her work in boxing saw him raise the profile of the sport in the country, fighting exhibitions and working as a trainer. She would clearly kick start the female boxing movement in Japan, long before any of the others, and was a key factor in careers for the likes of Miki Kikukawa and Yumi Takano. She pre-dates the like of Feujin Raika by years and also played a role in showing that fighters could convert from one of Japan's other combat sports leagues. Although Miyuki is only "officially" listed at 1-1 we know that's wrong, due to footage of her and reliable sources, we her impact it still being felt, directly and indirectly to this very day!
5-Naoya Inoue (17-0, 15) - International man of focus
It's hard to really figure out where Naoya Inoue sits in this list. He hasn't inspired a generation of fighters, he hasn't forced rules to change, he hasn't set up a gym, or played a part in the running of the sport. However what he has done, internationally, has drawn eyes to Japanese boxing, he has managed to capture an international audience like no other Japanese fighter, getting American and European fans talking, and featuring as a cover star for magazines that often put Japanese boxing down their list of priorities. He has, arguably, become the first Japanese fighter, in a long time, to become a global star. His real influence is likely to be more notable in the Reiwa era, but it's impossible to state how much he has done since his debut in 2012. He, more than any other fighter, has made Japanese boxing global and we expect that will be something felt for a very, very long time.
4-Hiroki Ioka (33-8-1, 17) - First generation Ioka!
Today Kazuto Ioka is one of the biggest names in Japanese boxing. His unclue, Hiroki Ioka, is however a man who deserves on any list of influential fighters. The talented former 2-weight world champion saw his career begin before the Heisei era but his influence grew through out the era. He won his first world title in 1987, 3 months before the Heisei era began, but would make his first defense just weeks after the new emperor took the throne. He went 22-8-1 (11) during the Heisei era, defending the WBC Minimumweight title and winning the WBA Light Flyweight title. He would also chase a third divisional world title, coming up short at both Flyweight and Super Flyweight. After retiring in 1998 he would turn his hand to promoting, inspire his nephew to fight and guide numerous careers, as well as working as part of the West Japan Boxing Association. His influence may often be over-looked but he has been incredibly influential and will continue to be so in the Kansai region.
3-Katsunari Takayama (31-9-0-1, 12) - Rule changing road warrior
It's hard to ignore just how influential Katsunari Takayama was to Japanese boxing during his 40 fight career. The Minimumweight warrior was a trend setter who pushed his dreams and forced the JBC, and the JABF, to change how they did things. His pursuit of the IBF and WBO world titles eventually helped their legitimacy in Japan, and played a part in getting the JBC to recognise both the titles. He also brought real attention to the Minumumweight division, in part thanks to his incredible fight with Francisco Rodriguez Jr. He also, very notable, pushed the JABF into allowing former professional fighters to return to the amateur ranks. Whilst Takayama will never go down as one of the all time greats, it's impossible to ignore the effect that his career had on Japanese boxing.
2-Hideyuki Ohashi (19-5, 12) - The Phoenix
In the west Hideyuki Ohashi is relatively unknown, though plays a massive role in Japanese boxing, and has done for over 30 years. At the start of the Heisei era Ohashi was 9-3 (5) though went 10-2 (7) during the rule of Emperor Akihito, becoming a 2-time Minimumweight world champion during that 12 bout run. What he's he's done since hanging up the gloves in 1993 has been amazing, and he has not only played a role in the governing of Japanese boxing, due to roles with the JBC and JPBA, but also ran the Ohashi Gym. That gym has given us the likes of Katsushige Kawashima, Akira Yaegashi and Naoya Inoue. The "Ohashi Gym" is one of the most significant in Japan right now and looks to go from strength to strength.
Koki Kameda - Insanely popular, controversial, and a real star. His effect as a fighter was divisive but few can argue that he's not, even in retirement, a major draw.
Kiyoshi Hatanaka - A massive figure in boxing in Chubu, formerly a fighter and now the region's leading promoter with the likes of Kosei Tanaka and Kento Hatanaka making their name under him
Akinobu Hiranaka - Huge punching fighter who's work in Okyama as a promoter has started to build a notable, and exciting, local scene
Toshiaki Nishioka - Japan's fighters have tended to stay at home, fighting in the confines of of Japan. Nishioka would be one of the few fighters to go out of Japan for fighters on a semi-regular basis. He would fight in the US, Mexico and France during his career and prove that Japanese fighters could win away from home.
Yoshihiro Kamegai - Who spoke about Naoya Inoue dragging eyes to the Japanese scene. The same can also be said of Yoshihiro Kamegai, who actually became a bigger name in the west than in Japan, thanks to his fun to watch brawls. We wouldn't suggest many fighters follow his style, but his mind set of making it big in the US has helped lead the way for others.
Ryota Murata - It's unclear how much influence Murata has, or hasn't had. His TV figures are huge, his popularity, even now, is massive, but the real influence is the intangible, and that's the amateur success. We've yet to see Japanese amateurs really flourish on the international stage since Murata's 2012 Olympic gold medal, but it's expected that the 2020 Olympics will be a very successful one for Japan. It's assumed that Murata's amateur triumph may potentially have a similar effect to Amir Khan, who won an Olympic medal in 2004 and saw the UK team have a massive games in 2012.
1-Joichiro Tatsuyoshi (20-7-1, 14) - A generational influence
Few fighters can match the influence that Joichiro Tatsuyoshi had to the current Japanese scene. "Joe" made his debut 8 months after the start of the Heisei era and fought through to 2009, albeit with some breaks in there. During his career he would be a 2-time WBC Bantamweight champion, and whilst he was fast tracked to a title his influence was less due to his title reigns and more his style, his personality and his charisma. His effect on Japanese boxing was inspiring a generation of fighters, helping to kick start the current era of Japanese boxing. Even now he is still insanely popular, and when he appears at ring, as a member of the crowd, the cameras regularly zoom in on him. Enigmatic, exciting and incredibly charismatic the Osakan is still a star, though had had to pay for his boxing with various issues now effecting him.
With all the “world” titles out there it's hard to believe that we've only ever had two Japanese fighters who have been 3-weight world champions. The first of those was the controversial Koki Kameda (33-1, 18) whilst the second was Kazuto Ioka (17-1, 10), who achieved the feat earlier this week.
Whilst the recognition of being “3 weight world champions” is something they share, it's certainly not the only thing they have in common. Both have been backed by Japanese TV giant TBS, both made their names at a very young age, both were born in Osaka and both have been fast tracked to the top, winning their first titles very quickly.
Here we'll be taking a look at how the two men match up in their achievements so far, and what the future is likely to deliver for both men.
Kameda, born in 1986, began his career in 2003 as a promising and exciting young fighter. In less than 3 years Kameda claim his first world title, the previously vacant WBA Light Flyweight title, as he narrowly out pointed Juan Jose Landaeta in a controversial split decision. That was Kameda's 12th professional bout and whilst the win was highly controversial he did set the record straight with a clearer win in a rematch just 4 months later. Sadly however that was Kameda's only defense at the weight.
Ioka, born in 1989, made his debut soon after turning 20 and began his career at Light Flyweight. Like Kameda however he dropped down a weight for his first world title bout which came less than 2 years after his debut. Unlike Kameda there was no doubting Ioka's first title win as he stopped long reigning champion Oleydong Sithsamerchai in the 5th round of their bout to claim the WBC Minimumweight title. That was just Ioka's 7th professional bout and saw him setting a then Japanese record, which has since been broken by Naoya Inoue and looks likely to be beaten again in May by Kosei Tanaka.
Whilst Kameda vacated his title and moved up after just one defense Ioka decided he'd hang around a bit and recorded a trio of title defenses. The most notable of those saw him unifying the WBC and WBA titles with a razor thin win over fellow Japanese fighter Akira Yaegashi. The win over Yaegashi really was a fight that saw Ioka mounting a claim to being the #1 in the division but he did move up immediately afterwards.
Kameda's second title reign began in 2009 when he claimed the WBC and Linear Flyweight title with an excellent win over Daisuke Naito. The bout was filled with lot bad feeling between the two men due issues between Naito and the Kameda family following Naito's bout with Koki's younger brother Daiki and that bad feeling helped draw massive interest in the bout. Sadly however it wasn't the most exciting of bouts with Kameda being too good and too quick for the then 35 year old Naito, who would only fight once more before retiring. This really was Kameda's stand out win, and came in fight #22, sadly however it quickly followed by his first loss as Pongsaklek Wonjongkam out pointed him in what Kameda's first defense of the title.
In total Kameda's first two reigns consisted of just a single successful defense. A disappointing return but one that had seen him mix with good company and hold a linear title.
Ioka's second reign began at the end of 2012 when he claimed the previously vacant WBA Light Flyweight title, the same title that Kameda had held in 2006, with a 6th round TKO against Jose Alfredo Rodriguez. As the champion here Ioka defended the belt with defenses against Thai veterans Waisanu Kokietgym and Kwanthai Sithmorseng as well the previously unbeaten Felix Alvarado.
Whilst his was frustrating, despite the excellent win over Alvarado, it's fair to say that Ioka's reign here was of a “secondary” title. The real WBA champion was super champion Roman Gonzalez and although talks of the two fighting did exist the bout never came off with Ioka's team taking the blame. Interestingly however Gonzalez never defended his title whilst Ioka held the “regular” title and instead the Nicaraguan great flirted with the Flyweight division that he later moved to.
Kameda's third reign was at Bantamweight and began less than 9 months after his loss to Wonjongkam. It saw Kameda skipping the Super Flyweight division and going straight to Bantamweight where he claimed the previously vacant WBA title with a decision win over former Super Flyweight champion Alexander Munoz. Kameda's reign here lasted significantly longer than either of his previous two and saw him making 8 defenses. The reign began in Kameda's 25th bout making him one of the quickest fighters to become a 3-weight world champion, doing it in 2 less fights than American Adrien Broner and 9 less fights than Flord Mayweather Jr.
On paper Kameda's reign sounds great however there was a lot to dislike about it. Several defenses were close with split decisions over Hugo Ruiz, Panomroonglek Kaiyanghadaogym and the unheralded Jung Oh Son, there was also less than inspiring defenses, not only against Son but also Nouldy Manakane, Mario Macias and John Mark Apolinario. Not only were the defenses generally lacking but this was secondary title, with Anselmo Moreno holding the “Super title”. Sadly Kameda vacated the title soon before he was supposed to go to purse bids with Moreno and instead said he was dropping to Super Flyweight.
For Ioka his third has just begun and it started when he won the WBA Flyweight title with a close and very competitive win over Juan Carlos Reveco. The win came in Ioka's 18th professional bout, making him the quickest fighter in history to become a 3-weight world champion. This was however his shot at a Flyweight title after having previously come up short against Amnat Ruenroeng in an IBF title fight.
This is a secondary title, with Juan Francisco Estrada holding the “super” title but it's still a notable win over a very good title holder and a win that puts him in the mix for really big fights down the line.
The future for both men looks to be really interesting.
For Kameda the next step is clear. He'll be fighting against Kohei Kono in a battle for the WBA Super Flyweight title at some point in the next few months. That will give give Kameda a chance to become the first 4 weight world champion from Japan. Not only is the future bright for his legacy but also financially following a link up with powerful American promoter Al Haymon.
Sadly for Kameda he is now an “out cast” from the Japanese boxing scene and is, along with his brothers, banned from fighting at home and even if he wins the WBA Super Flyweight title he'll be seen as a “lesser” champion, well behind WBO champion Naoya Inoue.
As for Ioka the future is less clear though arguably more exciting. He is still TBS's boxing poster child, he has the money behind him to bring top opponents to Japan though where he goes next could well be very interesting. There is a possibility of a rematch with Reveco, Ruenroeng or Alvarado there is also possible show downs with Juan Francisco Estrada, Roman Gonzalez or defenses against people like Brian Viloria, Koki Eto, Giovani Segura and Suguru Muranaka.
Ioka may only have a “secondary” title but given the division he is in there is so much to be excited about and so many brilliant match ups for him there the future looks wonderfully exciting. Sadly however we really can't see him moving to Super Flyweight any time soon so a potential super fighter with Inoue is highly unlikely, so to is a fight with Kameda or Kono. Given his age we'll never say never, but becoming a 4 weight world champion doesn't likely for Ioka.
